Overview

This savings rate calculator helps you estimate how much of your monthly income you save. Enter your income, monthly expenses, and savings contributions to quickly see your savings rate, monthly surplus, and estimated annual savings.

How it works

The calculator first works out your monthly surplus by subtracting expenses from income. It then calculates your savings rate as your monthly savings divided by your monthly income, shown as a percentage. It also estimates your yearly savings by multiplying your monthly savings by 12 and shows your expense ratio so you can compare saving and spending levels.

Frequently asked questions

What does this savings rate calculator estimate?

It estimates the percentage of your income you save each month, along with your monthly surplus and annual savings contributions.

What is a good savings rate?

A good savings rate depends on your goals, income, and living costs. In general, a higher savings rate can give you more flexibility and help you reach goals faster.

Should I use gross or net income?

You can use either, but be consistent. Many people prefer net income for personal budgeting because it reflects the money they actually receive.

Do investments count as savings?

Yes, if you regularly contribute money to investment or retirement accounts, many people count those contributions as savings.

Why is my monthly surplus different from my savings amount?

Your surplus is income minus expenses, while your savings amount is what you actually set aside. If they differ, some leftover money may be untracked or spent elsewhere.

Does this calculator include investment growth?

No. It only measures how much you save based on your monthly inputs, not any returns or interest earned later.
